Is there any chance to get LUT implementation similar to this: docs.unrealengine.com/latest/INT/Engine/...orGrading/index.html

The method above is a lot easier when trying to create a LUT gradient. You can simply take a screenshot of the default game, load it into your photo editing software and make the color corrections you want the image. Apply those same corrections to the LUT image and you are good to go.

I am not sure if you already have it setup this way, but at a glance it doesn't look like it.

Absolutely possible? MasterEffect can do it already, just saying.

Thanks Crosire.

Marty, I noticed you already had LUT implemented. I just don't know if it's the same method. In UE4 I can easily create an LUT with the colors I want by editing a screenshot of the game. I can then apply the same color edits to the LUT gradient. Is this the method you use? By the looks of it, the LUT you supply with MasterEffect is not a neutral gradient. Therefore any edits I want to make are guesses which make it really hard to get the results I want, as opposed to the method UE4 uses.

Anyway, just discussion. What you are doing is brilliant. Thank you.

It is a gradient from black to white which I already changed a bit to make its effect visible. If you want a neutral LUT without any color changing, let photoshop draw a gradient from left to right from black to white. Any tinting etc applied on this gradient results in same effect on final image.

I've tried starting with a basic gradient but it always darkens the image. Increasing the luminosity seems to only whitewash it while decreasing the luminosity only makes it more off.There appears to be no middle ground to start from? .And this is with all the other settings turned off except lut. I've been fighting with this all day...

I have a Palette pack that I got from ChinaGreenElvis and I Edited them to work as LUT with MasterFX if you are Interested.
They are giving me great Results.

I would very much love to check them out!

Pm me friend!

I checked out your initial post and read through the article, but I'm a bit lost. What they don't explain in the article is which channels pertain to what?

I've done this today

The code is based on this

in order to make it work you have to:
add the option in the customFX settings
#define ColorLUT    1
add this line in ReShade.fx
#include EFFECT(CustomFX, ColorLUT)
modify the original table with photoshop or similar, rename it lookup.png and put all in the CustomFX folder
Now it let you take an in-game screenshot with the lut in the top left corner modify it in photoshop and then the color correction is applied from this screenshot
